在_Layout.cshtml中将Layout设置为null [英] Setting Layout to null in _Layout.cshtml

问题描述

您是否有理由要在_Layout.cshtml中将Layout属性设置为null?

例如，像这样，在渲染主体视图之前?

For example, like this, before rendering the body view?

    ...
    <section id="content">
        @{ Layout = null; }
        @RenderBody()
    </section>
    ...

对我来说似乎很荒谬，删除行设置不会改变页面加载的工作方式.

It seems pretty nonsensical to me, and removing the line setting Layout doesn't change the way page loads work observationally.

是否有任何原因，您为什么要在_Layout.cshtml中设置Layout属性?

Is there any reason why you would want to set the Layout property in _Layout.cshtml?

推荐答案

布局页面也可以具有布局.在嵌套布局中，您有意使用 Layout 属性定义布局页面的超级布局.默认情况下，如果未指定，则在布局页面中为null.当您制作 @ {Layout = null} 时，您明确地说这是您的最终布局，因此它不嵌套在任何超级布局中.

Layout pages can have a layout too. In nested layouts , you intentionally use Layout property to define super layout of layout page . By default it is null in your layout page if you do not specify any. When you make @{Layout=null} you are explicitly saying that this your final layout so it is not nested in any super layout.
